  • Patent number: 10060436
    Abstract: A progressive vortex pump comprises an inlet housing in contact with the pumped fluid, a pump housing connected to the inlet housing, and an outlet housing connected to the pump housing and connected to a pumping pipe. The pump housing comprises a disc-shaped rotor having a central bore and a rim with vanes. Each rotor comprises at least one through hole along the axial direction, the through hole being positioned between the central bore and the rotor rim. Advantageously, the presence of a through hole on the rotor enables, under operating conditions, fluid exchange from the posterior fluid film to the anterior fluid film, thus promoting a pressure balance between the posterior and anterior fluid films, therefore enabling the rotor to work evenly, preventing rubbing on adjacent diffusers.

  • Patent number: 9995161
    Abstract: A turbocharger shaft is sealed with respect to the bore of the bearing housing at the turbine wheel end by one or more shaft seal rings. Conventionally these rings are seated in annular grooves provided in the shaft behind the turbine wheel. Problems can arise with this conventional shaft seal arrangement, particularly where the turbocharged engine has an engine brake valve located downstream of the turbine, and the back pressure in the exhaust line, and thus in the turbine wheel housing, can reach 7 bar. The inventive shaft seal design avoids grooves, and makes it possible to assemble a seal with ring seals with higher wear resistance and thus to maintain the seal's effectiveness over heavy use.

  • Patent number: 9989036
    Abstract: A wind turbine blade is described having a lightning bypass system located at the root end of the blade. The lightning bypass system comprises a stay bolt formed from an electrically insulating material having a conductive core. The conductive core of the stay bolt provides a conductive path for a lightning down conductor system through the root end of a wind turbine blade to the turbine hub or nacelle, bypassing any sensitive root end components of the wind turbine blade.
